The Sun Hydraulics DMDAXNV914 (DMDAXNV914) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and the ability to operate without minimum hydraulic pressure. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it is engineered to deliver precise control and reliable operation in various applications. This model features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The valve incorporates a wet armature design; the working fluid surrounds the armature which helps in heat dissipation but requires consideration regarding fluid selection as some fluids may degrade under prolonged exposure to heat. The DMDAXNV914 is equipped with EPDM seals suitable for use with phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. It also supports interchangeable coils with other Sun Series 1 solenoid products, offering flexibility in maintenance and replacement. Additionally, the valve features Sun's floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. This model can be manually overridden using a detent mechanism designed for temporary actuation, with an expected mechanical life of about 7,000 cycles. The manual override requires minimal force and has been optimized for ease of use under pressure conditions. Overall, the Sun Hydraulics DMDAXNV914 valve is a compact yet powerful solution for sophisticated hydraulic systems requiring reliable directional control and swift response times.
